Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed April '21, 1920. Serial No. 375,607.

To all whom it may concern:

Be it known that 1, JOHN D. NOBLE, a citizen of the United States, and resident of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and Improved Display Device, of which the following is a full, clear, and exact description.

This invention relates to a display device, and aims to provide a device of this character which shall provide an attractive advertising medium.

Revolving doors are often rotated by unthinking persons with such speed as to cause injury to persons subsequently entering the door. Further, a great amount of energy is wasted in a revolving door.

It is well appreciated that numerous stores are utilizing a moving display, with a view of providing an attractive medium.

My invention now contemplates to provide a regulator particularly applicable for use in connection with revolving doors which will prevent of a too rapid rotation of the same, and at the same time permit a utilizing of the energy now wasted in a door of this type.

A further object of my invention is the construction of a display device, which will act as an attractive advertising medium.

Reference is had to the attached sheets of drawings which illustrate practical embodiments of my invention, and in which drawings- Figure 1 is a partly sectional front view of a display device constructed in accordance with my invention, which view is taken along the lines 1-1 of Fig. 4.

Fig. 2 is a sectional side view the lines 2-2 of Fig. 1.

Fig. 3 is a sectional plan through the device.

Fig. 4: is a similar plan view taken along a slightly lower line through Fig. 1.

Fig. 5 and Fig. 6 illustrate certain details of construction utilized, and

Figs. 7 and 8 show a partly sectional front and plan view of a slightly modified form of my device.

In these views the reference numeral 10 designates a door revolving upon a shaft 11 in the conventional manner.

Doors of this nature are often provided with a roof turning with the door, and in the construction employed, 1 conveniently form the outer edge of this roof with gear teeth taken along view taken two trains of gears,

13 for a purpose hereinafter'specified. The upper end of the shaft 11 is extended through the roof and incasing portion of the door, and has conveniently secured to one end a beveled gear 13 of any suitable construction.

A display device conveniently including a rotatable drum 14 as has been illustrated in Figs. 1 to 6 inclusive is positioned at any desirable display point, this drum being conveniently mounted upon any desirable type of standards 15 carrying the mounting shaft 16 around which the drum revolves.

lVith a view of providing a connecting medium serving to transmit the power usually lost in a revolving door, two trains of gears are preferably employed, one of which conveniently includes a beveled gear 17 meshing with the gear 13, which beveled gear connects with and serves to rotate, a shaft 18 carrylng suitable gears 19, which in turn mesh with an mternal gear 20 ex tending inwardly from and secured to the inner face of the drum 14.

A second train of gears conveniently comprises any suitable type of gear 21, which meshes with the teeth 12 of the roof of the door 10, this latter gear having fix-.

edly associated with it a beveled gear 22, in turn meshing with a beveled gear 28 attached to the shaft 16. The gear 23 is fixedly associated with a second gear 24, which latter gear conveniently meshes with .the teeth of the gear 19.

In this connection it is to be noted that a second transversely extending shaft is provided below the shaft 16, which latter shaft also carries gears corresponding to the gears 19 of the upper shaft, by means of which power is transmitted to the display device at a number of different points.

It will thus be appreciated, that upon the door 10 being moved, that the drum 14 is revolved by means of the two trains of gears, which are accurately timed to provide synchronous movement.

It will be appreciated, that by providing that the strain is evenly divided so that very little danger of the wearing of the parts exists, and the leverage produced by the provision of these gears serves to permit a rotation of the drum 14 with the expenditure of but a minimum amount of energy in moving the door 10.

Referrin more particularly to the conbe seen that the construction therein embodied includes, as in the aforedescribed construction, two trains of gears of the construction aforementioned, an advertising medium in the nature of a turn table 25 being used. However, in this latter construction the turn table 25 is provided, adj acent its outer edge with upwardly extending teeth 26 engaged and moved by the lowermost of the gears 19, which, in this instance, are mounted upon stud shafts and brackets 27 in lieu of the transversely extending axles.

It will be appreciated that the latter construction provides a desirable display deconstruction.

Obviously numerous modifications of 20 structure might be resorted to without in the least departing from the scope of my claim, which reads,

A revolving door, including panels, a shaft mounting and permitting a revolving of said panels, a movable display device, and means interposed between said shaft and display device adapted to impart motion to the latter when the former is moved.

JOHN D. NOBLE.
